SLO'I'TING, SHAPING,

Application filed August 23, 1920.

To all 1137mm it may concern:

Be it known that we HAnoLi) BUTLER Hammer BUTLER, RICHARD HENRY HAY-HURs'r, and lViLFRED ALonesoN, of Victoria Ironworks, Halifax, England,have invented certain new and useful Improvements in Slotting.Slhapinggl hflilling, Drilling, and Other like Machine lools of whichthe following is a specification.

This invention relates to slot-ting machines, or v .rtical shapingmachines but it may also be applied to milling and drilling machines andit consists in providing means whereby work may be machined either atright angles to the table, or at an angle greater or less than 90 ateither side of the perpeiulicular.

F or this purpose instead ot the frame or body of the machine beingformed in one )lECB. the portion (hereinafter referred to as the upperpart) which carries the ram or other tool actuating device is hinged tothe portion (hereinafter referred to as the lower part) which carriesthe work table and means are provided for preserving the alignment o theaforesaid parts in a lateral disection.

In the accompanying drawing;

Fig". l is a side elevation of a slotting machine constructed inaccordance with this invention.

Fig. 2 is a horizontal section taken apniately on line 2-2 of Fig. l.and El shews a side and edge view oi an angle indicator lletached fromthe machine.

A. indicates the upper part, B the lower part. C the ram and D the worltable. The upper part is hinged to the lovv er part at a and isacci'irateiy fitted into such part by surfaces (4 which fitbetween facedces b 11 the lower part. The upper part is capable of being turned. toeither side ot the perpendicular, say. for through a distance of 10. Inthe example shown in the drawings this is effected by a. worm E keyed ona stud e in a bracket e that is attached. to the lower part B and suchworm gears with a toothed segment 0 attached to the upper part A. By theside of example pecifieation of Letters Patent.

Patented May 23, 19.22. Serial No. 405,299.

this segment is a graduated angle indicator which operates inconjunction with a tooth or setting mark 6 on the bracket 6. The stud eis provided with a hexagonal head 0 for engagement with a spanner orkey, or it may be provided with a handle, or hand wheel. When the upperpart has been adjusted to the required angle, it is securely locked tothe lower part by a draw bolt F and operating handle F A positive stopmay be provided to facilitate setting the upper part vertically to thework table I).

V7 hat we claim as our invention and desire to secure by Letters Patentof the United States is 1. In a vertical shaping machine, an upper tramepart hinged to a lower frame part, the said upper it'rame part havingtaced surfaces fitting accurately between faced surfaces on the lowerpart, a worm sector mounted on the upper parta worm mounted on the lowerpart and gearing with the worm sector, means tor actuating the worm.means for indicating the angle to which. the upper part has been movedand a draw bolt for securing" the upper part in any adjusted position.

2. In a vertical shaping machine, an upper frame part hinged to a lowerframe part, an axle passing through such parts and constituting a hingepin for the upper part, the said upper part having faced surfaces atopposite sides ot the avle fitting accurately between similarly placedfaced surfaces on the lower part, a worm sector mounted on the upperpart. worm mounted on the lowerpart and gearing with the worm sector in:ns for indicating the angle to which the upper part has been mo ed anddra bolt mounted in the lower part and passing through a slot in theupper part and means for ac-taiatin" said draw bolt to secure the upperpart i any adjusted position.

ln testimony whereof. we allix our signatures.
